M25/A3 drivers face overnight interchange closures

The project will see a new lane added to each of the carriageways of the A3

Drivers planning to use the A3 and M25 around Wisley in Surrey are being warned of overnight closures planned for this week and next weekend.

A long-term project to widen the A3 where it meets the M25 at the motorway's junction 10 has lead to a series of closures.

The latest, with two slip roads being shut, was due to be lifted by 06:00 on Monday.

From Monday to Thursday the whole interchange will be shut overnight, with drivers unable to join or leave either road at that junction, with daytime closures planned for the weekend.

Jonathan Wade, project director for National Highways, told BBC Radio Surrey: "You can expect to see some disruption from about 21:00.

"So long as you're travelling later at night, you should be OK.

"The following weekend, 17 and 18, for that whole weekend you will not be able to transition between the M25 and the A3 at all."

Traffic will be unable to transfer between the A3 and M25 at junction 10 during the overnight closures

The overnight closures are to allow for resurfacing work, with the weekend closures due to be in place from 21:00 BST on 16 May to 06:00 BST on 19 May.

The project is due or completion by Spring of 2026.

"I think there's an air of tolerance" said Mr Wade, "it is a nuisance and we recognise its a nuisance.

"It's an imposition on those travelling long distances and those who are impacted by these kind of activities."
